This converts the following to Kconfig:
   CONFIG_SYS_BOOT_RAMDISK_HIGH

We move the SYS_CACHE_SHIFT_N options from arch/arm/Kconfig to
arch/Kconfig, and introduce SYS_CACHE_SHIFT_4 to provide a size of 16.
Introduce select statements for other architectures based on current
usage.  For MIPS, we take the existing arch-specific symbol and migrate
to the generic symbol.  This lets us remove a little bit of otherwise
unused code.

All symbols that are defined in Kconfig will always be defined (or not)
prior to preprocessing due to the -include directive while building.
However, symbols which are not yet migrated will only be defined (or
not) once the board config.h is included, via <config.h>.  While the end
goal must be to migrate all symbols, today we have cases where the size
of gd will get mismatched within the build, based on include order.
Mitigate this by making sure that any <asm/global_data.h> that uses
symbols not in Kconfig does start with <config.h>.  Remove this when not
needed.

Migrate CONFIG_LMB in Kconfig.

At present it is not possible to include spl.h in on these architectures
since the asm/spl.h file is not present. We want to be able to use the
spl_phase() function, so add empty headers to make things build.

Move this uncommon header out of the common header.

Add support for CSM enable/disable and CSM relocation via
hsdk_init command. We allow to relocate CSM to the beginning of
any aperture even if HW support finer granularity.

In case of DSP extension presence in HW some instructions
(related to integer multiply, multiply-accumulate, and divide
operation) executes on this DSP execution unit. So their
execution will depend on dsp configuration register (DSP_CTRL)
As we want these instructions to execute the same way regardless
of DSP presence we need to set DSP_CTRL properly.

NOTE:
we do the same adjustments in Linux kernel, see in kernel tree:

Since version 3.0 ARC HS supports SL$ (L2 system level cache)
disable. So add support for SL$ disable/enable to code.

We add memory barriers for __raw_readX / __raw_writeX accessors same
way as it is done for readX and writeX accessors as lots of U-boot
driver uses __raw_readX / __raw_writeX instead of proper accessor
with barrier.

It will save us from lot's of debugging in the future and it is OK
as U-Boot is not that performance oriented as real run-time
software like OS or user bare-metal app so we may afford being not
super fast as we only being executed once.
